TROLLEY-WIRE SUPPORT.

Application inea March 20,'1909. serial No. 484,765.

i To all whom. it may concern:

v'itknewnthat-I, RorDEN O. CoUoH, a citizen of the Unit-edl States,residing at Charleston, m the county of Kanawha and tftate'of NestVirginia, haveinvented certain new `and uset'ul Improvements inTrolley-@Vire Supports, of which thetollowing is a specification. 4

lMy invention relates to wire supporters or hangers, but moreparticularly to hangers for electric trolley-Wires and. has for its pur#pose to` provide a device of that character which -is applicable to beitted to insulators of any standard or special type; and whereinthemeans for securing` the hanger toits supporter serves also as themeans t'oi' securing the trolley-wire to the hanger; thus avoiding theuse of intermediate fastening means-for the latter'.

IThe further purpose of the present invention 1s to provide a hangerofsuch structure that by reason of its manner of attachment,` to theinsulator will' effectively strengtheniv the joint between them, whichjoint in the i present used type of hangers is their point` of greatestweakness. The device is kpurposely designed to meet certain'reipii-reinents of thetrolley railway system in mines and it has otheradvantages rendering it particularly useful in that service, whichadvantaies'will be pointed out in the course ot' the `iollowingdescription vand set torthin the claims.` l

ln the accompanying drawing wherein is shown my invention in itspreferred structure, Figure 1 isa transverse sectional View of thesaine, and Fig. 2l is a view 1n perspective showing parts of the devicesegregated.

Referring t0 the figures in further detailand wherein like numerals ofreference indis corresponding parts in both views, 1 -i .-ignates aninsulating or base block to which the hanger proper is secured. The.block 1 .isof substantially cylindrical design and is `jovided vwith anaperture therethrouglii'forlhe reception of .a securingbolt 2 having apointed .screw threaded end` 3 by means of which the base block is fixedin position. 'lhe head tot the securing bolt 2 i" is incased within thespace `between the hanger members and being thus shielded is guardedfrom such obstructions as would otherwise tend toloosen the bolt. A Theupper marginal edge of the insulator block 1 is provided. witha-.depending or oveihanging ledge 5, the purpose whereof is to serve asa water shed for the insulator block and thereby increase the insulatingetiect of the support as a whole by shedding thewater from' the hangerproper.

The trolley-wire engaging means coinprises [substantially a clamp formedof two like inenibers, which members are for their greater part ofsemi-cylindrical design and .have on their inner faces and coexte'nsivewith the widtl'i'thereof ridges 7 adapted to BEST AvAiLAeLE ooFY4v titwithin a .complementary annular' groove 7a formed within theinsulatingblock 1.

To effect amore perfect union between the member of the clamp and thebase block, and.

vent relative movement between them and at the Sametime to permit aclearance'for the trolley-wheel of thecar. Both' of the members t3 haveformed on their lower portions enlargements 1l and 13 which are per`rtorated in alinement for the passage of a tie or securing bolt. 9 whichwith the nut 12 constitutes the means tor holding the clamp to theinsulator block 1 and also as the means for engaging the clamp with thetrolley-wire and holding the latter-'in suspension. The aperture throughthat portion 11 is of polygonal design in cross section whereby toreceive and hold againstl relative turninginoveineiit a like designedshank10 of the bolt 9. That' portion 13 is so disposed with relationtothe body of the 'clamp proper that there is 4'freedom ofl movement forthe turning of he nut 12,

and whereby the nut and that end of the bolt in engagement therewith,arewthin the plane o the sides of the clamp members: In order that thedevice may .be used in dierent parts of amine, there'is provided' anoifstanding lug 15 recessed to receive the end of the feed wire.provided on each of the clamping inen'ibers a perforated'lug 1G whichwhen the parts are assembled provides a strain ear forja ystay wire.

'lo cover the overall dimensions of the insulator block and the severalparts secured thereon thereY is av metallic plate or shed 17 disposed ontop of the insulator 1 and held in that position by the bolt Q whichpasses centrally through-'said plate. The water shed is furtherserviceable in that it gives a seat or even base for the insulator blockl and thus enables a betterl positioning of the trolley-wire. l

lIn order that the hanger may be readily suspended from a span wire,wire 18, there is provided on the upper face of the plate 1T a pair ofoppositely disposed lugs it), each of which is under-cut and has acurved face 20 of substantially the saine contour as that of thespanwire. Goperative -with the lugs 19 is a peripherally grooved and`circular block 21 formed integrally with the platel?, and interposedbetween the nut 23 and the block 21 is a rubber and an iron washer Q4and Q4 adapted to prevent Water from ruiming down upon the insulator.'l`lie span' wire ii'tting within the groove is oit-set with respect tothe lugs 1S) and is thus held against relative movement with the hanger.But the device is not restricted to this method of suspension; on thecontrary it is obvious that the pointed screw threaded end-3 of the bolt:2 adapts said bolt to enter a timber oi' other fixed part suitable forsuspension oi the insulator and in this latter method of suspension, thenut 23 can, of course be omitted, if desired.

From the foregoing description, itwill be vseen that by the peculiarmanner of assembling the several parts of the trolleywire support theinsulator block 1 servesl as a fulcruin for the clamp members 6 withrespect to the trolley-wire 14 and in turn the trolley-dre 14 serves asa fulcruin with respect to the insulator block 1, the bolt i) thusserving the double purpose oi effect-ing a se cure union between thoseparts,

.Having thus described my invention what I claim as new therein' anddesire to secure by Letters Patent is 1.
